For a demonstration, a professor uses a razor blade to cut a thin slit in a piece of aluminum foil. When she shines a laser pointer (? = 682 nm) through the slit onto a screen 5.0 m away, a diffraction pattern appears. The bright band in the center of the pattern is 5.0 cm wide. What is the width of the slit?
